Join the power movement as Head of Power Origination Commercial fusion energy is the holy grail for providing limitless, clean, firm energy that is safe, secure and ultimately affordable. And while this power is not yet available today, CFS is working every day to try to pull that fusion future forward, focusing first on our SPARC demonstration plant outside Boston and then our ARC fusion power plants, the first of which is expected to be online in the early 2030s. The Head of Power Origination will take a leading role in identifying, engaging with, and executing customer and partnership strategies and deals for those future ARC power plants. You will lead the commercialization, market entry, and structured contracting, playing an active role in transforming how this new form of clean, resilient power gets contracted and deployed. In this role, you will define and execute our commercial origination strategy. Reporting to the Head of Power Business, you will lead energy customer development and secure long-term offtake agreements—building and translating our pipeline into committed contracts, capital, and bankable assets. You will be on the front line of engaging with these customers and partners working creatively and partnering closely with project development, finance, legal, and engineering, to craft, negotiate, and secure these commercial agreements. You will serve as a key leader of the commercial team, driving the deployment of clean, safe, and abundant fusion energy.

Join the power movement as a Staff Supplier Integration Manager - ARC CFS confronts exciting but significant challenges associated with the supply chain for ARC and other new products and projects. Key challenges for ARC include: (a) producing a design that leads to a very cost competitive and producible (deployable) product (b) managing high levels of technical uncertainty and (c) an expensive and operationally difficult path to begin building ARC power plants. The Staff Supplier Integration Manager (SSIM) will create and execute global supply chain strategies fully integrated with CFS design teams and in close partnership with other functions including R&D, business and corporate development, Open Innovation, and government affairs. This strategy development will include focused and highly technical efforts to improve and simplify CFS designs with practical knowledge of supply chain capabilities, focused on major improvements to product cost and other key metrics. It will require deep, continuous, and insightful research into new technologies, evolving market conditions, and other key trends. The SSIM will also conduct global, creative and systematic supplier searches, and build and manage complex, senior-level supplier relationships. Finally, the SSIM will lead negotiation of long-term, high-value agreements that will be pivotal to CFS’ ability to build and deploy key products such as ARC. The SSIM must be an established expert in technical sourcing, able to speak the languages of plasma physicists, engineers and material scientists. The SSIM must be experienced and comfortable in uncertain, unstructured, low Technology Readiness Level (TRL) environments, while exercising curiosity and creativity to identify and understand new trends and technologies. The SSIM should be capable of serving as the senior face of CFS to supplier executives and other external audiences, during difficult negotiations and other interactions. Internally, the SSIM should be able to speak directly to the Executive Leadership Team about how design and technical decisions translate into the supply of hardware, including associated cost, risk, etc. and should understand how to marshal internal resources and consensus in support of project objectives.

Combining decades of research, top talent, and new technologies, we’re designing and building commercially viable fusion power plants. And we're working with policymakers, suppliers, and many others to build the energy industry of the future. We’re in the best position to make it happen. Since 2018, we’ve raised $4 billion of capital, making us the largest and leading fusion company in the world. Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team. If that’s you and this role fits, we want to hear from you. Join the power movement as a Staff Scientist - Plasma Material Interaction The plasma facing components (PFCs) in SPARC and ARC are the hardware interface between high performance burning plasmas and the entire tokamak. Due to the extreme plasma conditions needed for fusion, the PFCs will see heat and particle loads that far exceed most other domains of science and engineering. The Scientist - Plasma Material Interaction (PMI) provides a critical interface between plasma physics, materials science, and nuclear engineering. The Scientist will be organizationally based in the Plasma Physics Department with designated technical contacts in the Materials Science and Nuclear Engineering Departments. By connecting computational plasma physics models, engineering models, neutronics models, and material models, the Scientist will enable predictive modeling of the coupled evolution of PFC materials and the plasma, across timescales ranging from seconds to years. The ultimate objective of these coupled workflows is to inform the design and operation of the plasma facing components for ARC, a 400MWe fusion power plant to be delivered in the early 2030s. In order to validate and verify the workflows, the Scientist will oversee test campaigns at experimental facilities around the world, exploring PMI and neutron loading. Additionally, the Scientist will have access to Deuterium-Tritium experimental data from the SPARC tokamak, and the predictive workflows will be benchmarked using this CFS data. It is expected that through the aforementioned efforts the Scientist will develop a deep understanding of the material degradation associated with plasma loading and fusion neutron irradiation, and will represent CFS as a world expert in this domain.

Join the power movement as a Senior Process Engineer CFS is looking for a Senior Process Engineer with deep chemical engineering fundamentals and experience designing, scaling up, commissioning, and operating process systems in large industrial facilities. The ideal candidate comes from an industry such as power generation, petrochemical processing, liquefied natural gas (LNG), industrial gases, chemicals, air separation, cryogenic refrigeration, pulp & paper, or another large-scale process industry. You understand how to translate fundamental process requirements into practical industrial systems and have taken designs from early concepts through Front-End Loading (FEL), detailed engineering, construction, commissioning, start-up, and operation. Fusion power plants bring together process technologies that traditionally span multiple industries. At CFS, you will have the opportunity to work across cryogenic systems including helium and nitrogen, power generation and steam systems, molten salt systems, fueling and gas processing, vacuum systems, and process utilities such as cooling water and instrument air. We are looking for an engineer who understands how these systems behave in the real world because they have personally designed, built, commissioned, operated, or troubleshot industrial process equipment. You should be equally comfortable developing a process design basis, building a heat and material balance, sizing equipment, originating and owning P&IDs, leading a HAZOP, walking down installed piping, supporting start-up, and diagnosing why an operating system is not performing as designed.
